Each character used to be able to store a bunch of guns in their bank and a second character could store a bunch of guns in their bank. And a third character could store a bunch of guns in their bank.
I understand the idea you were going for here with the expanded shared storage, but without INDIVIDUAL storage being also an option, you end up with way less space for items than Borderlands 2.
That seems counter to the advertising of more guns. A singular shared 50 slot bank for however many characters I want to make is insanely small.
If Diablo was your original inspiration, you’re way below them at this point for gear storage.
